Abstract

Treatment of poultry feces with Tolura sp. CH-30 produced a material that was significantly deodorized and showed a promotive effect on plant growth. Tolura sp. CH-30 grew on the poultry feces, deodorizing the feces by assimilation of volatile fatty acids, which are the source of the offensive odor, as a carbon source. Significant degradation of uric acid also occurred. In the treatment of feces with Tolura sp. CH-30, it was possible to deodorize feces in a short time, but reduction in the amount of urate-N was not enough. Urate-N inhibited plant growth due to an excessive nitrogen content produced as a result of rapid decomposition. Therefore, we propose a recycle-treatment plan using poultry feces treated with Tolura sp. CH-30. After the recycle-treatment, the amount of urate-N contained in the recycle-treated poultry feces was small and the recycle-treated poultry feces showed a promotive effect on plant growth when it was added at a nitrogen content of 1.6 g/600 g soil/pot.
